As shown in Table 4 and Figures 1C,D, clinical stage, tumor grade, and H19 rs2839698 (CT/TT vs. CC) were associated with RCC survival in univariate analysis; in multivariate analysis, clinical stage was found to be the best prognostic factor for RCC survival, followed by tumor grade (P < 0.001, HR = 15.5; 95% CI = 5.94–40.34 and P = 0.004, HR = 3.98; 95% CI = 1.55–10.23, respectively). The gene discussed is H19; the disease is renal cell adenocarcinoma.
